BACKGROUND OF THE INVENTION

Scatter factor (SF; also known as hepatocyte growth factor [HGF], and hereinafter referred to and abbreviated as HGF/SF) is a pleiotropic growth factor that stimulates cell growth, cell motility, morphogenesis and angiogenesis. HGF/SF is produced as an inactive monomer (˜100 kDa) which is proteolytically converted to its active form. Active HGF/SF is a heparin-binding heterodimeric protein composed of a 62 kDa α chain and a 34 kDa β$ chain. HGF/SF is a potent mitogen for parenchymal liver, epithelial and endothelial cells (Matsumoto, K, and Nakamura, T. 1997, Hepatocyte growth factor (HGF) as a tissue organizer for organogenesis and regeneration. Biochem. Biophys. Res. Commun. 239, 639-44; Boros, P. and Miller, C. M., 1995, Hepatocyte growth factor: a multifunctional cytokine. Lancet 345, 293-5). It stimulates the growth of endothelial cells and also acts as a survival factor against endothelial cell death (Morishita, R, Nakamura, S, Nakamura, Y, Aoki, M, Moriguchi, A, Kida, I, Yo, Y, Matsumoto, K, Nakamura, T, Higaki, J, Ogihara, T, 1997, Potential role of an endothelium-specific growth factor, hepatocyte growth factor, on endothelial damage in diabetes. Diabetes 46:138-42). HGF/SF synthesized and secreted by vascular smooth muscle cells stimulates endothelial cells to proliferate, migrate and differentiate into capillary-like tubes in vitro (Grant, D. S, Kleinman, H. K., Goldberg, I. D., Bhargava, M. M., Nickoloff, B. J., Kinsella, J. L., Polyerini, P., Rosen, E. M., 1993, Scatter factor induces blood vessel formation in vivo. Proc. Natl. Acad. Sci. USA 90:1937-41; Morishita, R., Nakamura, S., Hayashi, S., Taniyama, Y., Moriguchi, A., Nagano, T., Taiji, M., Noguchi, H., Takeshita, S., Matsumoto, K., Nakamura, T., Higaki, J., Ogihara, T., 1999, Therapeutic angiogenesis induced by human recombinant hepatocyte growth factor in rabbit hind limb ischemia model as cytokine supplement therapy. Hypertension 33:1379-84). HGF/SF-containing implants in mouse subcutaneous tissue and rat cornea induce growth of new blood vessels from surrounding tissue. HGF/SF protein is expressed at sites of neovascularization including in tumors (Jeffers, M., Rong, S., Woude, G. F., 1996, Hepatocyte growth factor/scatter factor-Met signaling in tumorigenicity and invasion/metastasis. J. Mol. Med. 74:505-13; Moriyama, T., Kataoka, H., Koono, M., Wakisaka, S., 1999, Expression of hepatocyte growth factor/scatter factor and its receptor c-met in brain tumors: evidence for a role in progression of astrocytic tumors Int. J. Mol. Med. 3:531-6). These findings suggest that HGF/SF plays a significant role in the formation and repair of blood vessels under physiologic and pathologic conditions. Further discussion of angiogenic proteins may be found in U.S. Pat. Nos. 6,011,009 and 5,997,868, both of which are incorporated herein by reference in their entireties.

Pharmaceutically acceptable derivatives thus include among others pro-drugs. A pro-drug is a derivative of a compound, usually with significantly reduced pharmacological activity, which contains an additional moiety, which is susceptible to removal in vivo yielding the parent molecule as the pharmacologically active species. An example of a pro-drug is an ester, which is cleaved in vivo to yield a compound of interest. Another example is an N-methyl derivative of a compound, which is susceptible to oxidative metabolism resulting in N-demethylation, particularly on the 1 position of the 3(5)-monosubstituted pyrazole derivatives of the invention. Pro-drugs of a variety of compounds, and materials and methods for derivatizing the parent compounds to create the pro-drugs, are known and may be adapted to the present invention. Certain exemplary pharmaceutical compositions and pharmaceutically acceptable derivatives will be discussed in more detail herein below.

The term “tautomerization” refers to the phenomenon wherein a proton of one atom of a molecule shifts to another atom. See, Jerry March, Advanced Organic Chemistry: Reactions, Mechanisms and Structures, Fourth Edition, John Wiley & Sons, pages 69-74 (1992). The term “tautomer” as used herein, refers to the compounds produced by the proton shift. For example, compounds of formula II (and more generally, compounds of formula II where R¹ is hydrogen), can exist as a tautomer as shown below:

Thus, the present invention encompasses the 3-monosubstituted pyrazole compounds described herein (e.g., compounds of formula I, II, and related formulae II^(A), II^(B), II^(C), etc. . . . ), as well as their tautomeric 5-monosubstituted pyrazole counterparts. Likewise, any compound shown as 5-monosubstituted pyrazole embraces its corresponding 3-monosubstituted tautomer.

The term “C(5)-positional isomer” as used herein refers to 1,5-disubstituted counterparts of the 1,3-disubstituted pyrazole compounds described herein. For example, the invention encompasses compounds of the formula (III^(B)) and its C(5)-positional isomer (III^(B′)):

Thus, whether or not explicitly specified, the present invention encompasses the 1,3-disubstituted pyrazole compounds described herein (e.g., compounds of formula I, III, and related formulae III^(A), III^(B), III^(C), III^(D), etc.), as well as their C(5)-positional pyrazole counterparts. Likewise, any compound shown as 1,5-disubstituted pyrazole embraces its corresponding 1,3-disubstituted positional isomer.

By the term “protecting group”, as used herein, it is meant that a particular functional moiety, e.g., O, S, or N, is temporarily blocked so that a reaction can be carried out selectively at another reactive site in a multifunctional compound. In preferred embodiments, a protecting group reacts selectively in good yield to give a protected substrate that is stable to the projected reactions; the protecting group must be selectively removed in good yield by readily available, preferably nontoxic reagents that do not attack the other functional groups; the protecting group forms an easily separable derivative (more preferably without the generation of new stereogenic centers); and the protecting group has a minimum of additional functionality to avoid further sites of reaction. As detailed herein, oxygen, sulfur, nitrogen and carbon protecting groups may be utilized. For example, in certain embodiments, as detailed herein, certain exemplary oxygen protecting groups are utilized. These oxygen protecting groups include, but are not limited to methyl ethers, substituted methyl ethers (e.g., MOM (methoxymethyl ether), MTM (methylthiomethyl ether), BOM (benzyloxymethyl ether), PMBM or MPM (p-methoxybenzyloxymethyl ether), to name a few), substituted ethyl ethers, substituted benzyl ethers, silyl ethers (e.g., TMS (trimethylsilyl ether), TES (triethylsilylether), TIPS (triisopropylsilyl ether), TBDMS (t-butyldimethylsilyl ether), tribenzyl silyl ether, TBDPS (t-butyldiphenyl silyl ether), to name a few), esters (e.g., formate, acetate, benzoate (Bz), trifluoroacetate, dichloroacetate, to name a few), carbonates, cyclic acetals and ketals. In certain other exemplary embodiments, nitrogen protecting groups are utilized. These nitrogen protecting groups include, but are not limited to, carbamates (including methyl, ethyl and substituted ethyl carbamates (e.g., Troc), to name a few) amides, cyclic imide derivatives, N-Alkyl and N-Aryl amines, imine derivatives, and enamine derivatives, to name a few. Certain other exemplary protecting groups are detailed herein, however, it will be appreciated that the present invention is not intended to be limited to these protecting groups; rather, a variety of additional equivalent protecting groups can be readily identified using the above criteria and utilized in the present invention. Additionally, a variety of protecting groups are described in “Protective Groups in Organic Synthesis” Third Ed. Greene, T. W. and Wuts, P. G., Eds., John Wiley & Sons, New York: 1999, the entire contents of which are hereby incorporated by reference.

As used herein, the term “isolated” when applied to the compounds of the present invention, refers to such compounds that are (i) separated from at least some components with which they are associated in nature or when they are made and/or (ii) produced, prepared or manufactured by the hand of man.

As used herein the term “biological sample” includes, without limitation, cell cultures or extracts thereof; biopsied material obtained from an animal (e.g., mammal) or extracts thereof; and blood, saliva, urine, feces, semen, tears, or other body fluids or extracts thereof; or purified versions thereof. For example, the term “biological sample” refers to any solid or fluid sample obtained from, excreted by or secreted by any living organism, including single-celled micro-organisms (such as bacteria and yeasts) and multicellular organisms (such as plants and animals, for instance a vertebrate or a mammal, and in particular a healthy or apparently healthy human subject or a human patient affected by a condition or disease to be diagnosed or investigated). The biological sample can be in any form, including a solid material such as a tissue, cells, a cell pellet, a cell extract, cell homogenates, or cell fractions; or a biopsy, or a biological fluid. The biological fluid may be obtained from any site (e.g. blood, saliva (or a mouth wash containing buccal cells), tears, plasma, serum, urine, bile, seminal fluid, cerebrospinal fluid, amniotic fluid, peritoneal fluid, and pleural fluid, or cells therefrom, aqueous or vitreous humor, or any bodily secretion), a transudate, an exudate (e.g. fluid obtained from an abscess or any other site of infection or inflammation), or fluid obtained from a joint (e.g. a normal joint or a joint affected by disease such as rheumatoid arthritis, osteoarthritis, gout or septic arthritis). The biological sample can be obtained from any organ or tissue (including a biopsy or autopsy specimen) or may comprise cells (whether primary cells or cultured cells) or medium conditioned by any cell, tissue or organ. Biological samples may also include sections of tissues such as frozen sections taken for histological purposes. Biological samples also include mixtures of biological molecules including proteins, lipids, carbohydrates and nucleic acids generated by partial or complete fractionation of cell or tissue homogenates. Although the sample is preferably taken from a human subject, biological samples may be from any animal, plant, bacteria, virus, yeast, etc. The term animal, as used herein, refers to humans as well as non-human animals, at any stage of development, including, for example, mammals, birds, reptiles, amphibians, fish, worms and single cells. Cell cultures and live tissue samples are considered to be pluralities of animals. In certain exemplary embodiments, the non-human animal is a mammal (e.g., a rodent, a mouse, a rat, a rabbit, a monkey, a dog, a cat, a sheep, cattle, a primate, or a pig). An animal may be a transgenic animal or a human clone. If desired, the biological sample may be subjected to preliminary processing, including preliminary separation techniques.

It will be appreciated that each of the compounds described herein and each of the subclasses of compounds described above (1-MI) may be substituted as described generally herein, or may be substituted according to any one or more of the subclasses described above and herein [e.g., i)-liv)].

Some of the foregoing compounds can comprise one or more asymmetric centers, and thus can exist in various isomeric forms, e.g., stereoisomers and/or diastereomers. Thus, inventive compounds and pharmaceutical compositions thereof may be in the form of an individual enantiomer, diastereomer or geometric isomer, or may be in the form of a mixture of stereoisomers. In certain embodiments, the compounds of the invention are enantiopure compounds. In certain other embodiments, mixtures of stereoisomers or diastereomers are provided.

Furthermore, certain compounds, as described herein may have one or more double bonds that can exist as either the Z or E isomer, unless otherwise indicated. The invention additionally encompasses the compounds as individual isomers substantially free of other isomers and alternatively, as mixtures of various isomers, e.g., racemic mixtures of stereoisomers. In addition to the above-mentioned compounds per se, this invention also encompasses pharmaceutically acceptable derivatives of these compounds and compositions comprising one or more compounds of the invention and one or more pharmaceutically acceptable excipients or additives.

Compounds of the invention may be prepared by crystallization of compound of formula (I), (II) and (III) under different conditions and may exist as one or a combination of polymorphs of compound of general formula (I), (II) and (III) forming part of this invention. For example, different polymorphs may be identified and/or prepared using different solvents, or different mixtures of solvents for recrystallization; by performing crystallizations at different temperatures; or by using various modes of cooling, ranging from very fast to very slow cooling during crystallizations. Polymorphs may also be obtained by heating or melting the compound followed by gradual or fast cooling. The presence of polymorphs may be determined by solid probe NMR spectroscopy, IR spectroscopy, differential scanning calorimetry, powder X-ray diffractogram and/or other techniques. In some embodiments, the present invention provides an amorphous compound of formula (I), (II) and (III). Preparation of amorphous solid forms are known in the art and include lyophilization and spray drying. Thus, the present invention encompasses inventive compounds, their derivatives, their tautomeric forms, their stereoisomers, their C(5)-positional isomer their polymorphs, their pharmaceutically acceptable salts their pharmaceutically acceptable solvates and pharmaceutically acceptable compositions containing them. Tautomeric forms of compounds of the present invention include, for example the 3- and 5-substituted pyrazole tautomers of any of the aforementioned disubstituted compounds of general Formula II and related formulas. Likewise, C(5)-positional isomers of the 1,3-disubstituted pyrazoles of general Formula I and III and related formulas are encompassed within the scope of the present invention. Thus, the invention encompasses 1,5-disubstituted pyrazoles.

2) Pharmaceutical Compositions

As discussed above this invention provides new formulations and compositions of compounds that have biological properties useful for the treatment of any of a number of conditions or diseases in which HGF/SF or the activities thereof have a therapeutically useful role, or in some instances, where antagonism thereof is useful. Such compounds are described in U.S. Pat. Nos. 7,192,976; 7,250,437; and 7,265,112, all of which are incorporated herein by reference in their entireties.

Accordingly, in another aspect of the present invention, pharmaceutical compositions and formulations are provided which comprise any one or more of the compounds described herein (or a prodrug, pharmaceutically acceptable salt or other pharmaceutically acceptable derivative thereof), and a pharmaceutically acceptable carrier. In certain embodiments, these compositions optionally further comprise one or more additional therapeutic agents. In certain embodiments such one or more agents are antiapoptotic, angiogenic or antifibrotic agents. Alternatively, a compound of this invention may be administered to a patient in need thereof in combination with the administration of one or more other therapeutic agents. For example, additional therapeutic agents for conjoint administration or inclusion in a pharmaceutical composition with a compound of this invention may be an approved agent to treat the same or related indication, or it may be any one of a number of agents undergoing approval in the Food and Drug Administration that ultimately obtain approval for the treatment of any disorder related to HGF/SF activity. It will also be appreciated that certain of the compounds of present invention can exist in free form for treatment, or where appropriate, as a pharmaceutically acceptable derivative thereof. According to the present invention, a pharmaceutically acceptable derivative includes, but is not limited to, pharmaceutically acceptable salts, esters, salts of such esters, or a pro-drug or other adduct or derivative of a compound of this invention which upon administration to a patient in need is capable of providing, directly or indirectly, a compound as otherwise described herein, or a metabolite or residue thereof.

As used herein, the term “pharmaceutically acceptable salt” refers to those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like, and are commensurate with a reasonable benefit/risk ratio. Pharmaceutically acceptable salts of amines, carboxylic acids, and other types of compounds, are well known in the art. For example, S. M. Berge, et al. describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 66: 1-19 (1977), incorporated herein by reference. The salts can be prepared in situ during the final isolation and purification of the compounds of the invention, or separately by reacting a free base or free acid function with a suitable reagent, as described generally below. For example, a free base function can be reacted with a suitable acid. Furthermore, where the compounds of the invention carry an acidic moiety, suitable pharmaceutically acceptable salts thereof may, include metal salts such as alkali metal salts, e.g. sodium or potassium salts; and alkaline earth metal salts, e.g. calcium or magnesium salts. Examples of pharmaceutically acceptable, nontoxic acid addition salts are salts of an amino group formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid and perchloric acid or with organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid or malonic acid or by using other methods used in the art such as ion exchange. Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hernisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, picrate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate, undecanoate, valerate salts, and the like. Representative alkali or alkaline earth metal salts include sodium, lithium, potassium, calcium, magnesium, and the like. Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, loweralkyl sulfonate and aryl sulfonate.

Additionally, as used herein, the term “pharmaceutically acceptable ester” refers to esters that hydrolyze in vivo and include those that break down readily in the human body to leave the parent compound or a salt thereof. Suitable ester groups include, for example, those derived from pharmaceutically acceptable aliphatic carboxylic acids, particularly alkanoic, alkenoic, cycloalkanoic and alkanedioic acids, in which each alkyl or alkenyl moiety advantageously has not more than 6 carbon atoms. Examples of particular esters include formates, acetates, propionates, butyrates, acrylates and ethylsuccinates.

Furthermore, the term “pharmaceutically acceptable prodrugs” as used herein refers to those prodrugs of the compounds of the present invention which are, within the scope of sound medical judgment, suitable for use in contact with the issues of humans and lower animals with undue toxicity, irritation, allergic response, and the like, commensurate with a reasonable benefit/risk ratio, and effective for their intended use, as well as the zwitterionic forms, where possible, of the compounds of the invention. The term “prodrug” refers to compounds that are rapidly transformed in vivo to yield the parent compound of the above formula, for example by hydrolysis in blood, or N-demethylation of a compound of the invention where R¹ is methyl. A thorough discussion is provided in T. Higuchi and V. Stella, Pro-drugs as Novel Delivery Systems, Vol. 14 of the A.C.S. Symposium Series, and in Edward B. Roche, ed., Bioreversible Carriers in Drug Design, American Pharmaceutical Association and Pergamon Press, 1987, both of which are incorporated herein by reference. By way of example, N-methylated pro-drugs of the 3(5)-monosubstituted pyrazoles of the invention are embraced herein.

As described above, the pharmaceutical compositions of the present invention additionally comprise a pharmaceutically acceptable carrier, which, as used herein, includes any and all solvents, diluents, or other liquid vehicle, dispersion or suspension aids, surface active agents, isotonic agents, thickening or emulsifying agents, preservatives, solid binders, lubricants and the like, as suited to the particular dosage form desired. Remington's Pharmaceutical Sciences, Sixteenth Edition, E. W. Martin (Mack Publishing Co., Easton, Pa., 1980) discloses various carriers used in formulating pharmaceutical compositions and known techniques for the preparation thereof. Except insofar as any conventional carrier medium is incompatible with the compounds of the invention, such as by producing any undesirable biological effect or otherwise interacting in a deleterious manner with any other component(s) of the pharmaceutical composition, its use is contemplated to be within the scope of this invention. Some examples of materials which can serve as pharmaceutically acceptable carriers include, but are not limited to, sugars such as lactose, glucose and sucrose; starches such as corn starch and potato starch; cellulose and its derivatives such as sodium carboxymethyl cellulose, ethyl cellulose and cellulose acetate; powdered tragacanth; malt; gelatine; talc; excipients such as cocoa butter and suppository waxes; oils such as peanut oil, cottonseed oil; safflower oil, sesame oil; olive oil; corn oil and soybean oil; glycols; such as propylene glycol; esters such as ethyl oleate and ethyl laurate; agar; buffering agents such as magnesium hydroxide and aluminum hydroxide; alginic acid; pyrogen-free water; isotonic saline; Ringer's solution; ethyl alcohol, and phosphate buffer solutions, as well as other non-toxic compatible lubricants such as sodium lauryl sulfate and magnesium stearate, as well as coloring agents, releasing agents, coating agents, sweetening, flavoring and perfuming agents, preservatives and antioxidants can also be present in the composition, according to the judgment of the formulator.

In one embodiment, liquid compositions or liquid formulations comprising compounds of the invention are provided that have increased solubility as compared to compounds of the invention dissolved in aqueous buffer such as phosphate-buffered saline. In one embodiment, such liquid compositions with increased solubility are provided by a composition comprising polyethylene glycol, polysorbate or a combination thereof. In one embodiment, the polyethylene glycol is polyethylene glycol 300. In another embodiment the polysorbate is polysorbate 80. In another embodiment the polyethylene glycol is present at about 40% to about 60% (v/v). In another embodiment the polysorbate is present at about 5% to about 15% (v/v). In another embodiment the polyethylene glycol is present at about 50% (v/v). In another embodiment the polysorbate is present at about 10% (v/v). In one formulation, the polyethylene glycol is present at 50% (v/v) together with polysorbate 80 at 10% (v/v). The balance of the solution can be a saline solution, a buffer or a buffered saline solution, such as phosphate-buffered saline. The pH of the solution can be from about pH 5 to about pH 9, and in other embodiments, about from pH 6 to about pH 8. In one embodiment the pH of the buffer is 7.4. In the foregoing embodiments, the compound of the invention is soluble at a concentration higher than in buffer alone, and can be present at about 0.8 to about 10 milligrams per milliliter of solution, or even higher. These formulations offer the preparation of convenient dosing solutions of practical volumes for single dose administration, by any route, in particular a parenteral route. In one embodiment, the route is intravenous, subcutaneous or intraperitoneal. Such compositions with a higher solubility permit achievement of more elevated blood concentrations that provide efficacy when the a threshold Cmax (maximal blood concentration after administration) should be achieved for optimal efficacy.

In certain embodiments, the compounds in the aforementioned compositions and formulations include (E)-3(5)-[2-(2,3-methylenedioxyphenyl)vinyl]-1H-pyrazole, (Z)-3 (5)-[2-(2,3-methylenedioxyphenyl)vinyl]-1H-pyrazole, (E)-3 (5)-[2-(2-chloro-5-trifluoromethylphenyl)vinyl]-1H-pyrazole, (Z)-3(5)-[2-(2-chloro-5-trifluoromethylphenyl)vinyl]-1H-pyrazole, (E)-3 (5)-[2-(2-trifluoromethylphenyl)vinyl]-1H-pyrazole, (Z)-3 (5)-[2-(2-trifluoromethylphenyl)vinyl]-1H-pyrazole, (E)-3(5)-[2-(2-furyl)vinyl]-1H-pyrazole, (Z)-3 (5)-[2-(2-furyl)vinyl]-1H-pyrazole, (E)-3 (5)-[2-(2-thienyl)vinyl]-1H-pyrazole, (Z)-3 (5)-[2-(2-thienyl)vinyl]-1H-pyrazole, (E)-3-(2-(5-nitrofuran-2-yl)vinyl)-1H-pyrazole, (Z)-3-(2-(5-nitrofuran-2-yl)vinyl)-1H-pyrazole, (E)-3-styryl-1H-pyrazole, (Z)-3-styryl-1H-pyrazole, (E)-2-(2-(1H-pyrazol-3-yl)vinyl)-1H-indole, (Z)-2-(2-(1H-pyrazol-3-yl)vinyl)-1H-indole, (E)-4-(2-(1H-pyrazol-3-yl)vinyl)-N,N-dimethylaniline, (Z)-4-(2-(1H-pyrazol-3-yl)vinyl)-N,N-dimethylaniline, (E)-3-(4-methoxystyryl)-1H-pyrazole, (Z)-3-(4-methoxystyryl)-1H-pyrazole, (E)-3-(2,6-dichlorostyryl)-1H-pyrazole, (Z)-3-(2,6-dichlorostyryl)-1H-pyrazole, (E)-3-(2-(naphthalen-2-yl)vinyl)-1H-pyrazole, (Z)-3-(2-(naphthalen-2-yl)vinyl)-1H-pyrazole, (E)-3-(2-(1H-pyrrol-2-yl)vinyl)-1H-pyrazole, (Z)-3-(2-(1H-pyrrol-2-yl)vinyl)-1H-pyrazole, (E)-3-(2-(thiophen-3-yl)vinyl)-1H-pyrazole, (Z)-3-(2-(thiophen-3-yl)vinyl)-1H-pyrazole, (E)-3-(2-(1H-pyrrol-3-yl)vinyl)-1H-pyrazole, (Z)-3-(2-(1H-pyrrol-3-yl)vinyl)-1H-pyrazole, (E)-3-(2-(furan-3-yl)vinyl)-1H-pyrazole, and (Z)-3-(2-(furan-3-yl)vinyl)-1H-pyrazole. These are merely exemplary and non-limiting. Other exemplary compounds are described in U.S. Pat. No. 6,610,726.

Liquid dosage forms for oral administration include, but are not limited to, pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylformamide, oils (in particular, cottonseed, groundnut (peanut), corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents.

Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution, suspension or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables. In one embodiment, the polyethylene glycol-polysorbate formulation described above is useful for injectable administration.

Such injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.

In order to prolong the effect of a drug, it is often desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension or crystalline or amorphous material with poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution that, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered drug form is accomplished by dissolving or suspending the drug in an oil vehicle. Injectable depot forms are made by forming microencapsule matrices of the drug in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of drug to polymer and the nature of the particular polymer employed, the rate of drug release can be controlled. Examples of other biodegradable polymers include (poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions that are compatible with body tissues.

Compositions for rectal or vaginal administration are preferably suppositories which can be prepared by mixing the compounds of this invention with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active compound.

In other embodiments, solid dosage forms of compounds embodied herein are provided. In some embodiment, such solid dosage forms have improved oral bioavailability. In one embodiment, a formulation is prepared in a solid formulation comprising about 20% (w/w) compound of the invention, about 10-20% (w/w) GELUCIRE® 44/14, about 10-20% (w/w) vitamin E succinate (TPS), 0 to about 60% polyethylene glycol 400, 0 to about 40% Lubrasol, 0 to about 15% Cremophor RH 40 (w/w), and about 1% (w/w) BHT.

The present invention encompasses pharmaceutically acceptable topical formulations of inventive compounds. The term “pharmaceutically acceptable topical formulation”, as used herein, means any formulation which is pharmaceutically acceptable for intradermal administration of a compound of the invention by application of the formulation to the epidermis. In certain embodiments of the invention, the topical formulation comprises a carrier system. Pharmaceutically effective carriers include, but are not limited to, solvents (e.g., alcohols, poly alcohols, water), creams, lotions, ointments, oils, plasters, liposomes, powders, emulsions, microemulsions, and buffered solutions (e.g., hypotonic or buffered saline) or any other carrier known in the art for topically administering pharmaceuticals. A more complete listing of art-known carriers is provided by reference texts that are standard in the art, for example, Remington's Pharmaceutical Sciences, 16th Edition, 1980 and 17th Edition, 1985, both published by Mack Publishing Company, Easton, Pa., the disclosures of which are incorporated herein by reference in their entireties. In certain other embodiments, the topical formulations of the invention may comprise excipients. Any pharmaceutically acceptable excipient known in the art may be used to prepare the inventive pharmaceutically acceptable topical formulations. Examples of excipients that can be included in the topical formulations of the invention include, but are not limited to, preservatives, antioxidants, moisturizers, emollients, buffering agents, solubilizing agents, other penetration agents, skin protectants, surfactants, and propellants, and/or additional therapeutic agents used in combination to the inventive compound.

In certain embodiments, the pharmaceutically acceptable topical formulations of the invention comprise at least a compound of the invention and a penetration enhancing agent. The choice of topical formulation will depend or several factors, including the condition to be treated, the physicochemical characteristics of the inventive compound and other excipients present, their stability in the formulation, available manufacturing equipment, and costs constraints. As used herein the term “penetration enhancing agent” means an agent capable of transporting a pharmacologically active compound through the stratum corneum and into the epidermis or dermis, preferably, with little or no systemic absorption. A wide variety of compounds have been evaluated as to their effectiveness in enhancing the rate of penetration of drugs through the skin. See, for example, Percutaneous Penetration Enhancers, Maibach H. I. and Smith H. E. (eds.), CRC Press, Inc., Boca Raton, Fla. (1995), which surveys the use and testing of various skin penetration enhancers, and Buyuktimkin et al., Chemical Means of Transdermal Drug Permeation Enhancement in Transdermal and Topical Drug Delivery Systems, Gosh T. K., Pfister W. R., Yum S. I. (Eds.), Interpharm Press Inc., Buffalo Grove, Ill. (1997). In certain exemplary embodiments, penetration agents for use with the invention include, but are not limited to, triglycerides (e.g., soybean oil), aloe compositions (e.g., aloe-vera gel), ethyl alcohol, isopropyl alcohol, octolyphenylpolyethylene glycol, oleic acid, polyethylene glycol 400, propylene glycol, N-decylmethylsulfoxide, fatty acid esters (e.g., isopropyl myristate, methyl laurate, glycerol monooleate, and propylene glycol monooleate) and N-methylpyrrolidone.

In certain embodiments, the compositions may be in the form of ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants or patches. In certain exemplary embodiments, formulations of the compositions according to the invention are creams, which may further contain saturated or unsaturated fatty acids such as stearic acid, palmitic acid, oleic acid, palmito-oleic acid, cetyl or oleyl alcohols, stearic acid being particularly preferred. Creams of the invention may also contain a non-ionic surfactant, for example, polyoxy-40-stearate. In certain embodiments, the active component is admixed under sterile conditions with a pharmaceutically acceptable carrier and any needed preservatives or buffers as may be required. Ophthalmic formulation, eardrops, and eye drops are also contemplated as being within the scope of this invention. Formulations for intraocular administration are also included. Additionally, the present invention contemplates the use of transdermal patches, which have the added advantage of providing controlled delivery of a compound to the body. Such dosage forms are made by dissolving or dispensing the compound in the proper medium. As discussed above, penetration enhancing agents can also be used to increase the flux of the compound across the skin. The rate can be controlled by either providing a rate controlling membrane or by dispersing the compound in a polymer matrix or gel.

It will also be appreciated that the compounds and pharmaceutical compositions of the present invention can be formulated and employed in combination therapies, that is, the compounds and pharmaceutical compositions can be formulated with or administered concurrently with, prior to, or subsequent to, one or more other desired therapeutics or medical procedures. The particular combination of therapies (therapeutics or procedures) to employ in a combination regimen will take into account compatibility of the desired therapeutics and/or procedures and the desired therapeutic effect to be achieved. It will also be appreciated that the therapies employed may achieve a desired effect for the same disorder (for example, an inventive compound may be administered concurrently with another anti-inflammatory agent), or they may achieve different effects (e.g., control of any adverse effects). In non-limiting examples, one or more compounds of the invention may be formulated with at least one cytokine, growth factor or other biological, such as an interferon, e.g., alpha interferon, or with at least another small molecule compound. Non-limiting examples of pharmaceutical agents that may be combined therapeutically with compounds of the invention include: antivirals and antifibrotics such as interferon alpha, combination of interferon alpha and ribavirin, Lamivudine, Adefovir dipivoxil and interferon gamma; anticoagulants such as heparin and warfarin; antiplatelets e.g., aspirin, ticlopidine and clopidogrel; other growth factors involved in regeneration, e.g., VEGF and FGF and mimetics of these growth factors; antiapoptotic agents; and motility and morphogenic agents.

In certain embodiments, the pharmaceutical compositions of the present invention further comprise one or more additional therapeutically active ingredients (e.g., anti-inflammatory and/or palliative). For purposes of the invention, the term “Palliative” refers to treatment that is focused on the relief of symptoms of a disease and/or side effects of a therapeutic regimen, but is not curative. For example, palliative treatment encompasses painkillers, antinausea medications and anti-sickness drugs.

3) Research Uses, Clinical Uses, Pharmaceutical Uses and Methods of Treatment

Research Uses

According to the present invention, the inventive compounds may be assayed in any of the available assays known in the art for identifying compounds having the ability to modulate HGF/SF activity and in particular to agonize or mimic the activities of HGF/SF. For example, the assay may be cellular or non-cellular, in vivo or in vitro, high- or low-throughput format, etc.

Thus, in one aspect, compounds of this invention which are of particular interest include those with HGF/SF-like activity, which:

-   -   exhibit HGF/SF activity;     -   exhibit the ability to mimic or agonize HGF/SF activities;     -   stimulate cell proliferation;     -   exhibit anti-apoptotic activity;     -   exhibit antifibrotic activity;     -   exhibit angiogenic activity; and/or     -   are useful for the treatment of HGF/SF-related conditions,         diseases and disorders.

Clinical uses of compounds with HGF/SF-like activity. As noted above, effective formulations of inventive compounds described herein are useful for the treatment of the following non-limiting description of diseases and conditions. Moreover, compounds and compositions embodied herein have been found useful for treating such diseases and conditions after their onset or after the acute phase of the disease has manifest or occurred, wherein treatment starting from, or a single dose given from, hours to days after onset is found to be beneficial.

1. Fibrotic Liver Disease: Liver fibrosis is the scarring response of the liver to chronic liver injury; when fibrosis progresses to cirrhosis, morbid complications can develop. In fact, end-stage liver fibrosis or cirrhosis is the seventh leading cause of death in the United States, and afflicts hundreds of millions of people worldwide; deaths from end-stage liver disease in the United States are expected to triple over the next 10-15 years, mainly due to the hepatitis C epidemic 1. In addition to the hepatitis C virus, many other forms of chronic liver injury also lead to end-stage liver disease and cirrhosis, including other viruses such as hepatitis B and delta hepatitis, chronic alcoholism, non-alcoholic steatohepatitis, extrahepatic obstructions (stones in the bile duct), cholangiopathies (primary biliary cirrhosis and sclerosing cholangitis), autoimmune liver disease, and inherited metabolic disorders (Wilson's disease, hemochromatosis, and alpha-1 antitrypsin deficiency).

Treatment of liver fibrosis has focused to date on eliminating the primary injury. For extrahepatic obstructions, biliary decompression is the recommended mode of treatment whereas patients with Wilson's disease are treated with zinc acetate. In chronic hepatitis C infection, interferon has been used as antiviral therapies with limited response: ˜20% when used alone or ˜50% response when used in combination with ribavirin. In addition to the low-level of response, treatment with interferon with or without ribavirin is associated with numerous severe side effects including neutropenia, thrombocytopenia, anemia, depression, generalized fatigue and flu-like symptoms, which are sufficiently significant to necessitate cessation of therapy. Treatments for other chronic liver diseases such as hepatitis B, autoimmune hepatitis and Wilson's disease are also associated with many side effects, while primary biliary cirrhosis, primary sclerosing cholangitis and non-alcoholic fatty liver disease have no effective treatment other than liver transplantation.

The advantage of treating fibrosis rather than only the underlying etiology, is that antifibrotic therapies should be broadly applicable across the full spectrum of chronic liver diseases. While transplantation is currently the most effective cure for liver fibrosis, mounting evidence indicates that not only fibrosis, but even cirrhosis is reversible. Unfortunately patients often present with advanced stages of fibrosis and cirrhosis, when many therapies such as antivirals can no longer be safely used due to their side effect profile. Such patients would benefit enormously from effective antifibrotic therapy, because attenuating or reversing fibrosis may prevent many late stage complications such as infection, ascites, and loss of liver function and preclude the need for liver transplantation. The compounds of the invention are beneficial for the treatment of the foregoing conditions, and generally are antifibrotic and/or antiapoptotic agents for this and other organ or tissues.

2. Hepatic Ischemia-Reperfusion Injury: Currently, transplantation is the most effective therapeutic strategy for liver fibrosis. However, in spite of the significant improvement in clinical outcome during the last decade, liver dysfunction or failure is still a significant clinical problem after transplantation surgery. Ischemia-reperfusion (IR) injury to the liver is a major alloantigen-independent component affecting transplantation outcome, causing up to 10% of early organ failure, and leading to the higher incidence of both acute and chronic rejection. Furthermore, given the dramatic organ shortage for transplantation, surgeons are forced to consider cadaveric or steatotic grafts or other marginal livers, which have a higher susceptibility to reperfusion injury. In addition to transplantation surgery, liver IR injury is manifested in clinical situations such as tissue resections (Pringle maneuver), and hemorrhagic shock.

The damage to the postischemic liver represents a continuum of processes that culminate in hepatocellular injury. Ischemia activates Kupffer cells, which are the main sources of vascular reactive oxygen species (ROS) formation during the initial reperfusion period. In addition to Kupffer cell-induced oxidant stress, with increasing length of the ischemic episode, intracellular generation of ROS by xanthine oxidase and in particular mitochondria may also contribute to liver dysfunction and cell injury during reperfusion. Endogenous antioxidant compounds, such as superoxide dismutase, catalase, glutathione, alphatocopherol, and beta-carotene, may all limit the effects of oxidant injury but these systems can quickly become overwhelmed by large quantities of ROS. Work by Lemasters and colleagues, has indicated that in addition to formation of ROS, intracellular calcium dyshomeostasis is a key contributor to liver IR injury. Cell death of hepatocyte and endothelial cells in this setting is characterized by swelling of cells and their organelles, release of cell contents, eosinophilia, karyolysis, and induction of inflammation, characteristic of oncotic necrosis. More recent reports indicate that liver cells also die by apoptosis, which is morphologically characterized by cell shrinkage, formation of apoptotic bodies with intact cell organelles and absence of an inflammatory response.

Indeed, minimizing the adverse effects of IR injury could significantly increase the number of patients that may successfully undergo liver transplantation. Pharmacologic interventions that reduce cell death and/or enhance organ regeneration represent a therapeutic approach to improve clinical outcome in liver transplantation, liver surgery with vascular exclusion and trauma and can therefore reduce recipient/patient morbidity and mortality. The compounds of the invention are beneficial for the treatment of the foregoing conditions.

3. Cerebral Infarction. Stroke and cerebrovascular disease are a leading cause of morbidity and mortality in the US: at least 600,000 Americans develop strokes each year, and about 160,000 of these are fatal. Research on the pathophysiological basis of stroke has produced new paradigms for prevention and treatment, but translation of these approaches into improved clinical outcomes has proved to be painfully slow. Preventive strategies focus primarily on reducing or controlling risk factors such as diabetes, hypertension, cardiovascular disease, and lifestyle; in patients with severe stenosis, carotid endarterectomy may be indicated. Cerebral angioplasty is used investigationally, but the high restenosis rates observed following coronary angioplasty suggest this approach may pose unacceptable risk for many patients. Therapeutic strategies focus primarily on acute treatment to reduce injury in the ischemic penumbra, the region of reversibly damaged tissue surrounding an infarct. Thrombolytic therapy has been shown to improve perfusion to the ischemic penumbra, but it must be administered within three hours of the onset of infarction. Several neuroprotective agents that block specific tissue responses to ischemia are promising, but none have yet been approved for clinical use. While these therapeutic approaches limit damage in the ischemic penumbra, they do not address the underlying problem of inadequate blood supply due to occluded arteries. An alternative strategy is to induce formation of collateral blood vessels in the ischemic region; this occurs naturally in chronic ischemic conditions, but stimulation of vascularization via therapeutic angiogenesis has potential therapeutic benefit.

Recent advances in imaging have confirmed the pathophysiological basis of the clinical observations of evolving stroke. Analysis of impaired cerebral blood flow (CBF) in the region of an arterial occlusion supports the hypothesis that a central region of very low CBF, the ischemic core, is irreversibly damaged, but damage in surrounding or intermixed zones where CBF is of less severely reduced, the ischemic penumbra, can be limited by timely reperfusion. Plate recently reviewed the evidence suggesting that therapeutic angiogenesis may be useful for treatment or prevention of stroke. First, analysis of cerebral vasculature in stroke patients showed a strong correlation between blood vessel density and survival and a higher density of microvessels in the ischemic hemisphere compared to the contralateral region. Second, studies in experimental models of cerebral ischemia indicate expression of angiogenic growth factors such as vascular endothelial growth factor (VEGF) or HGF/SF is induced rapidly in ischemic brain tissue. Third, administration of VEGF or HGF/SF can reduce neuronal damage and infarct volume in animal models. Similar evidence provided the rationale for developing therapeutic angiogenesis for treating peripheral and myocardial ischemia, which has been shown to produce clinical improvements in early studies in humans. The compounds of the invention are beneficial for the treatment of the foregoing conditions.

4. Ischemic heart disease is a leading cause of morbidity and mortality in the US, afflicting millions of Americans each year at a cost expected to exceed $300 billion/year. Numerous pharmacological and interventional approaches are being developed to improve treatment of ischemic heart disease including reduction of modifiable risk factors, improved revascularization procedures, and therapies to halt progression and/or induce regression of atherosclerosis. One of the most exciting areas of research for the treatment of myocardial ischemia is therapeutic angiogenesis. Recent studies support the concept that administration of angiogenic growth factors, either by gene transfer or as a recombinant protein, augments nutrient perfusion through neovascularization. The newly developed, supplemental collateral blood vessels constitute endogenous bypass conduits around occluded native arteries, improving perfusion to ischemic tissue. Some of the best-studied cytokines with angiogenic activity are vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF) and hepatocyte growth factor/scatter factor (HGF/SF). The compounds of the invention are beneficial for the treatment of the foregoing conditions.

5. Renal Disease. Chronic renal dysfunction is a progressive, degenerative disorder that ultimately results in acute renal failure and requires dialysis as an intervention, and renal transplantation as the only potential cure. Initiating conditions of renal dysfunction include ischemia, diabetes, underlying cardiovascular disease, or renal toxicity associated with certain chemotherapeutics, antibiotics, and radiocontrast agents. Most end-stage pathological changes include extensive fibrinogenesis, epithelial atrophy, and inflammatory cell infiltration into the kidneys.

Acute renal failure is often a complication of diseases including diabetes or renal ischemia, procedures such as heminephrectomy, or as a side effect of therapeutics administered to treat disease. The widely prescribed anti-tumor drug cis-diamminedichloroplatinum (cisplatin), for example, has side effects that include a high incidence of nephrotoxicity and renal dysfunction, mainly in the form of renal tubular damage that leads to impaired glomerular filtration. Administration of gentamicin, an aminoglycoside antibiotic, or cyclosporin A, a potent immunosuppressive compound, causes similar nephrotoxicity. The serious side effects of these effective drugs restrict their use. The development of agents that protect renal function and enhance renal regeneration after administration of nephrotoxic drugs will be of substantial benefit to numerous patients, especially those with malignant tumors, and may allow the maximal therapeutic potentials of these drugs to be realized. The compounds of the invention are beneficial for the treatment of the renal diseases mentioned above.

6. Lung (Pulmonary) Fibrosis. Idiopathic pulmonary fibrosis (IPF) accounts for a majority of chronic interstitial lung diseases, and has an estimated incidence rate of 10.7 cases for 100,000 per year, with an estimated mortality of 50-70%. IPF is characterized by an abnormal deposition of collagen in the lung with an unknown etiology. Although the precise sequence of the pathogenic sequelae is unknown, disease progression involves epithelial injury and activation, formation of distinctive subepithelial fibroblast/myofibroblast foci, and excessive extracellular matrix accumulation. The development of this pathological process is preceded by an inflammatory response, often dominated by macrophages and lymphocytes, which is mediated by the local release of chemoattractant factors and upregulation of cell-surface adhesion molecules. Lung injury leads to vasodilatation and leakage of plasma proteins into interstitial and alveolar spaces, as well as activation of the coagulation cascade and deposition of fibrin. Fibroblasts migrate into this provisional fibrin matrix where they synthesize extracellular matrix molecules. In non-pathogenic conditions, excess fibrin is usually degraded by plasmin, a proteinase that also has a role in the activation of matrix metalloproteinases (MMPs). Activated MMPs degrade extracellular matrix and participate in fibrin removal, resulting in the clearance of the alveolar spaces and the ultimate restoration of injured tissues. In pathological conditions, however, these processes can lead to progressive and irreversible changes in lung architecture, resulting in progressive respiratory insufficiency and an almost universally terminal outcome in a relatively short period of time. Fibrosis is the final common pathway of a variety of lung disorders, and in this context, the diagnosis of pulmonary fibrosis implies the recognition of an advanced stage in the evolution of a complex process of abnormal repair. While many studies have focused on inflammatory mechanisms for initiating the fibrotic response, the synthesis and degradation the extracellular matrix represent the central event of the disease. It is this process that presents a very attractive site of therapeutic intervention.

The course of IPF is characterized by progressive respiratory insufficiency, leading to death within 3 to 8 years from the onset of symptoms. Management of interstitial lung disease in general, and in particular idiopathic pulmonary fibrosis, is difficult, unpredictable and unsatisfactory. Attempts have been made to use antiinflammatory therapy to reverse inflammation, relief, stop disease progression and prolong survival. Corticosteroids are the most frequently used antiinflammatory agents and have been the mainstay of therapy for IPF for more than four decades, but the efficacy of this approach is unproven, and toxicities are substantial. No studies have compared differing dosages or duration of corticosteroid treatment in matched patients. Interpretation of therapy efficacy is obscured by several factors including heterogeneous patient populations, inclusion of patients with histologic entities other than usual interstitial pneumonia, lack of objective, validated endpoints, and different criteria for “response.” Cytotoxic drugs such as Azathioprine and cyclophosphamide have also being used in combination with low dose oral corticosteroids. The results of such treatments vary from no improvement to significant prolongation of survival. Overall, currently available treatments for lung fibrosis are sub-optimal. Potential new therapies have emerged from the use of animal models of pulmonary fibrosis and recent advances in the cellular and molecular biology of inflammatory reactions. Such therapies involve the use of cytokines, oxidants and growth factors that are elaborated during the fibrotic reaction. Despite the use of newer strategies for treatment, the overall prognosis for patients with interstitial lung disease has had little quantifiable change, and the population survival remains unchanged for the last 30 years. Interferon gamma (IFN) may be effective in the treatment of IPF in some patients but its role is controversial. Literature indicated that IFN-gamma may be involved in small airway disease in silicosis lung. Others showed that IFN gamma mediates, bleomycin-induced pulmonary inflammation and fibrosis. Recently, hepatocyte growth factor (HGF), also known as scatter factor (SF) has emerged as a attractive target for the development of antifibrotic agents. The compounds of the invention are beneficial for the treatment of the foregoing condition, among other fibrotic diseases.

Exemplary Assays

Efficacy of the compounds of the invention on the aforementioned disorders and diseases or the potential to be of benefit for the prophylaxis or treatment thereof may be demonstrated in various studies, ranging from biochemical effects evaluated in vitro and effects on cells in culture, to in-vivo models of disease, wherein direct clinical manifestations of the disease can be observed and measured, or wherein early structural and/or functional events occur that are established to be involved in the initiation or progression of the disease. The positive effects of the compounds of the invention have been demonstrated in a variety of such assays and models, for a number of diseases and disorders. One skilled in the art can readily determine following the guidance described herein whether a compound of the invention is an HGF/SF mimic and is useful therapeutically in the same manner as HGF/SF, or is an antagonist and is useful where the activities of HGF/SF are not desired or are to be inhibited.

1. In Vitro Stimulation of Proliferation and Scatter

a. Endothelial cell proliferation. Proliferation of human umbilical vein endothelial cells and monkey bronchial epithelial cells ([³H]-thymidine incorporation) by compounds of the invention produce a response similar to that of HGF/SF.

b. Renal cell scatter. The ability to scatter cultured MDCK cells is highly specific for compounds with HGF/SF activity. Compounds of the invention scatter MDCK cells in a manner similar to HGF/SF.

2. Cellular Signaling

a. Phosphorylation of c-met. In both human umbilical vein endothelial cells (HUVECs) and MDCK cells the instant compounds induce phosphorylation of c-met in a dose-dependent manner similar to HGF/SF. The assay is performed by immunoprecipitation of phosphorylated c-met followed by SDS-PAGE and chemiluminescence detection, standardized to total c-met.

b. Intracellular signaling induced by compounds of the invention and HGF/SF. In HUVECs the compounds induce phosphorylation of extracellular receptor kinase (ERK) (as determined by immunoprecipitation followed by SDS-PAGE and chemiluminescence) similar to HGF/SF. In addition, the phosphoinositide 3-kinase inhibitor wortmannin and an Akt inhibitor prevents compound- and HGF/SF-induced endothelial cell proliferation, suggesting that both the instant compounds and HGF/SF exert biological effects through the same intracellular signaling pathways.

c. HGF and compounds of the invention stimulate nitric oxide production in endothelial cells. HUVECs are incubated with either vehicle, HGF/SF, instant compounds, or SNAP for 24 hours, loaded with the nitric oxide-sensitive fluorescence indicator DAF 2-DA and imaged under a laser scanning confocal microscope. HGF/SF, instant compounds and SNAP all cause a significant increase in fluorescence indicating robust production of nitric oxide.

3. Anti-Apoptotic Activity

a. HGF/SF and instant compounds have significant anti-apoptotic activity in cultured cell lines. Like HGF/SF, the compounds are able to significantly block adriamycin-induced apoptosis in MDCK cells. Pretreatment with either HGF/SF or compound significantly improves the cell viability of both HUVEC and MDCK cell lines.

b. Protection from apoptosis in NIH-3T3 cells transfected with c-met receptor. NIH-3T3 cells transfected with the gene for the c-met receptor confers the ability for both HGF/SF and compounds of the invention to protect the cells from adriamycin-induced apoptosis (MTT assay). There is no protection from apoptosis by compounds in non-transfected cells lacking the c-met receptor, demonstrating the requirement of c-met for the cyto-protective actions of HGF/SF and instant compounds.

4. Angiogenesis

a. Aortic ring assay. Thoracic artery rings from rats are embedded in Matrigel and grown for 5 days in the presence or absence of HGF/SF or compounds of the invention. Treatment with compounds of the invention causes an increased outgrowth from the rings similar to that seen with HGF/SF.

b. In vivo Matrigel assay. Matrigel mixed with a compound of the invention or vehicle is injected into the abdominal subcutaneous tissue of C57BL/6 mice. When harvested 10 days later, the compound is found to induce blood vessel formation into the Matrigel plugs, demonstrating that the compound can exert its angiogenic effects in vivo.

c. Mouse hindlimb ischemia model. In a mouse hindlimb ischemia model treatment with a compound of the invention produces greater recovery of hindlimb blow flow (as measured by laser Doppler imaging). Improved flux is associated with an increased number of capillaries in the ischemic muscle.

d. Hindlimb ischemia in non-obese diabetic (NOD) mice. In female NOD mice subjected to hindlimb ischemia, hindlimb blood flow (measured using a Laser Doppler imager) demonstrates recovery by administration of a compound of the invention.

e. Angiogenesis in full-thickness cutaneous wounds. In full thickness cutaneous wounds in pigs significant increases are observed in capillary numbers after treatment with a compound of the invention, or Ad5-HGF/SF (an adenoviral vector expressing the gene for HGF/SF).

5. Hepatic Disease

a. Antifibrotic Activity in Hepatic Stellate Cells. Serum starved (activated) LX2 cells (an immortalized human hepatic stellate cell line) that are treated with HGF/SF or a compound of the invention show a decrease in collagen I mRNA expression, as well as expression of other fibrotic marker genes, related to significant antifibrotic activity.

b. Liver Disease endpoints. The rat model of thioacetamide (TAA)-induced liver fibrosis and the rat bile duct ligation model of fibrosis showed improvements by the compounds of the invention, in a panel of functional and histological tests: gross morphology, mass, portal pressure, presence of ascites, enzymes (AST, ALT), collagen content, interstitial fibrosis and alpha-smooth muscle actin and MMP-2. Delayed treatment from the time of induction of disease shows significant benefit.

6. Protection Against Renal Dysfunction

a. Clinical model: arterial occlusion. In a mouse model of transient unilateral renal artery occlusion, male ICR mice were anesthetized and the left renal artery occluded with a microvascular clamp. After 30 minutes, the clamp was removed and the kidney allowed to reperfuse. Ten minutes into reperfusion the nonischemic contralateral kidney was excised. Animals were treated daily with vehicle or compound of the invention (1 mg/kg, i.p.) until the day of sacrifice. Serum creatinine, BUN and urine protein levels, measured at 1, 4 and 7 days postischemia were used to determine the ability of compounds of the invention to restore function to injured kidneys. In order to create a more severe renal injury, animals were subjected to 45 minutes of ischemia. In other models, permanent ligation/nephrectomy is carried out. Immediate as well as delayed treatment with embodied compounds is beneficial.

b. Protection against HgCl₂-induced renal injury. In a study mice were injected with a high dose of HgCl₂ (7 mg/kg, s.c.) and divided into treatment groups. Animals in the first group received vehicle or a compound of the invention (1 mg/kg, i.p.) on the day of toxin injection and daily thereafter for 3 days, and were euthanized on day 4. Blood samples collected prior to HgCl₂ injection, on day 2 and on day 4 were analyzed for serum creatinine. In the second group, treatment with vehicle or compound began on the day following toxin injection (i.e., 24 h delayed treatment) and daily thereafter until day 6. Mice were euthanized on day 7. Blood samples collected prior to HgCl₂ injection, on day 4 and day 7 were analyzed for serum creatinine and BUN. Serum creatinine, BUN, and development of tubular necrosis were measured to indicate positive clinical activity.

c. Protection against urethral obstruction. The effects of the compounds of invention on renal injury secondary to ureteral obstruction were examined in a mouse model of transient unilateral renal artery occlusion. Kidneys from mice subjected to unilateral ureteral obstruction for 2 weeks were examined for histological evidence of injury and protection by compound treatment. Immunohistochemical staining was performed for fibronectin, proliferating cell nuclear antigen, and TUNEL (for an assessment of apoptosis). Trichrome staining was also performed to assess the extent of collagen formation as an indication of interstitial fibrosis.

7. Cerebral infarction/stroke

a. Neuroprotective Effects in Brain Tissue. Cerebral infarction was induced in rats by middle cerebral artery occlusion (MCAO) for 24 hr. Test compound or vehicle was administered by i.p. at 2 mg/kg at −24, 0, and 8 hr. Sections of the brain were then examined for cell death by staining with a tetrazolium compound (2,3,5-Triphenyl-2H-tetrazolium chloride, or TTC). Normal rat brains exhibit a red staining due to TTC reduction whereas areas containing dead cells are white.

8. Myocardial Infarction

a. Ability of the compounds of the invention to inhibit apoptosis in a rat model of myocardial infarction (as mentioned above). Hearts from rats subjected to left coronary artery ligation are treated with compound (or vehicle control) by direct injection and 24 hours later sectioned and TUNEL stained. There is a significant reduction in the number of apoptotic nuclei in rats treated with compound.

b. Clinical model. In a rat ischemia model, myocardial infarction was induced by anterior descending artery occlusion. The infarction was evident by an increase in positive TUNEL staining, indicating DNA fragmentation in late-stage apoptosis. Treatment with compounds of the invention greatly reduced the extent of TUNEL staining.

c. Clinical model with delayed treatment. Treatment delayed for 24 hours after myocardial ischemia reduces infarct size.

9. Transplantation and Organ Preservation

a. The viability of organs and tissues harvested and transported for transplant is currently optimally maintained by bathing and transport in storage solutions such as the University of Wisconsin (UW) cold storage solution (100 mM KH₂PO₄, 5 mM MgSO₄ 100 mM potassium lactobionate, 1 mM allopurinol, 3 mM glutathione, 5 mM adenosine, 30 mM raffinose, 50 g/liter of hydroxyethyl starch, 40 units/liter of insulin, 16 mg/liter of dexamethasone, 200,000 units/liter of penicillin, pH 7.4; 320-330 mOsM) (Ploeg R J, Goossens D, Vreugdenhil P, McAnulty J F, Southard J H, Belzer F O. Successful 72-hour cold storage kidney preservation with UW solution. Transplant Proc. 1988 February; 20(1 Suppl 1):935-8.). To further enhance the viability of transplanted organs and tissues, inhibit apoptosis and promote vascularization thereof, one or more compounds of the invention may in included in this or any other storage solution, as well as perfused into the donor or donor organ prior to harvesting, and administered to the recipient systemically and/or locally into the transplanted organ or transplant site.

10. Lung Fibrosis

In order to assess the effects of C6 on pulmonary fibrosis we used a well-established mouse model of bleomycin-induced lung injury. Male C57BL/6 mice (20-30 g, n=10/group) were treated with bleomycin (0.06 U/20 gram body weight) or saline via intratracheal administration. Bleomycin-treated mice were divided into 2 groups. Compounds of the invention (1 mg/kg, i.p.) or vehicle was administered daily until sacrifice on day 12. Right lung samples from the mice were then harvested for analysis. Tissues were sectioned and stained with modified Masson's Trichrome and analyzed for interstitial fibrosis. The Ashcroft scale was used to obtain a numerical fibrotic score with each specimen being scored independently by two histopathologists, and the mean of their individual scores considered as the fibrotic score.

11. Diabetes Mellitus

a. Compounds of the invention reduces hyperglycemia in diabetic mice. Normal CD-1 mice were induced to develop hyperglycemia (diabetes) by i.v. injection with 100 mg/kg streptozotocin (STZ) followed by measurement of blood glucose in a week. The animals were treated with test compound at 2 mg/kg or vehicle daily starting the same day of STZ injection. Glucose samples were taken from the tail vein at day 7 with Ascensia ELITE blood glucose test strips (Bayer), and the blood glucose concentration was determined by glucose meters (Bayer). STZ induced diabetes, as shown by a significant increase in blood glucose levels compared to that in normal mice. Compounds of the invention reduced blood glucose levels.

12. Muscular dystrophy. In a genetic murine muscular dystrophy model, two months of intraperitoneal administration of a compound embodied herein reduced the elevation in creatine kinase, indicating a beneficial effect on the disease.

13. Amyotrophic lateral sclerosis. In SODG93A mouse model of ALS, daily compound administration starting at age 94 days (when neurofilament degeneration typically occurs) through day 122 significantly improved hindlimb pathology score vs. In addition, a stride test showed that treated animals showed improvement. Survival of the treated animals was also significantly (p<0.05) extended vs. vehicle-treated animals.

General Reaction Procedures:

Unless mentioned specifically, reaction mixtures were stirred using a magnetically driven stirrer bar. An inert atmosphere refers to either dry argon or dry nitrogen. Reactions were monitored either by thin layer chromatography, by proton nuclear magnetic resonance (NMR) or by high-pressure liquid chromatography (HPLC), of a suitably worked up sample of the reaction mixture.

General Work Up Procedures:

Unless mentioned specifically, reaction mixtures were cooled to room temperature or below then quenched, when necessary, with either water or a saturated aqueous solution of ammonium chloride. Desired products were extracted by partitioning between water and a suitable water-immiscible solvent (e.g. ethyl acetate, dichloromethane, diethyl ether). The desired product containing extracts were washed appropriately with water followed by a saturated solution of brine. On occasions where the product containing extract was deemed to contain residual oxidants, the extract was washed with a 10% solution of sodium sulphite in saturated aqueous sodium bicarbonate solution, prior to the aforementioned washing procedure. On occasions where the product containing extract was deemed to contain residual acids, the extract was washed with saturated aqueous sodium bicarbonate solution, prior to the aforementioned washing procedure (except in those cases where the desired product itself had acidic character). On occasions where the product containing extract was deemed to contain residual bases, the extract was washed with 10% aqueous citric acid solution, prior to the aforementioned washing procedure (except in those cases where the desired product itself had basic character). Post washing, the desired product containing extracts were dried over anhydrous magnesium sulphate, and then filtered. The crude products were then isolated by removal of solvent(s) by rotary evaporation under reduced pressure, at an appropriate temperature (generally less than 45° C.).

General Purification Procedures:

Unless mentioned specifically, chromatographic purification refers to flash column chromatography on silica, using a single solvent or mixed solvent as eluent. Suitably purified desired product containing elutes were combined and concentrated under reduced pressure at an appropriate temperature (generally less than 45° C.) to constant mass. Final compounds were dissolved in 50% aqueous acetonitrile, filtered and transferred to vials, then freeze-dried under high vacuum before submission for biological testing.

1) Synthesis of Exemplary Compounds:

Unless otherwise indicated, starting materials are either commercially available or readily accessibly through laboratory synthesis by anyone reasonably familiar with the art. Described generally below, are procedures and general guidance for the synthesis of compounds as described generally and in subclasses and species herein. In addition, synthetic guidance can be found in Kinoshita, M. et al. Bull. Chem. Soc. Jpn. 1987, 60, 2151-2162; Natchev, I. A. Tetrahedron 1988, 44, 1511-1522; Almirante, N. et al. Tetrahedron Lett. 1998, 39, 3287; and Bellassoued and Majidi, J. Org. Chem. 1993, 58, 2517-2522; the entire contents of which are hereby incorporated by reference.

Mono-substituted Pyrazoles (C(3) and C(5) Tautomers)

The skilled practitioner will recognize that C(3)- and C(5)-substituted 1H-pyrazole tautomers typically exist as mixtures which rapidly interconvert in solution. Because of this rapid proton transfer, 3- and 5-substituted pyrazole tautomers do not normally have separate existence. The tautomers may, however, exist in solution predominantly in one form. See, for example, T. L. Gilchrist, “Heterocyclic Chemistry” 2nd Edition, Longman Scientific and Technical, 1992; p 287; which is incorporated herein by reference.

Thus, the synthetic guidance provided herein is relevant to both 3- and 5-substituted pyrazole tautomers.

In certain exemplary embodiments, compounds of formula (II) where R³ is —CH═CH—R may be prepared as follows:

For example, the preparation of 4-bromocrotonaldehyde (3) may be achieved using a modification of a literature method (Kinoshita, M. et al. Bull. Chem. Soc. Jpn. 1987, 60, 2151-2162). Conversion of 3 to 4 may be carried out using the method described in the literature (Natchev, I. A. Tetrahedron 1988, 44, 1511-1522), involving treatment of aldehydes 3 with triethylorthoformate in the presence of ammonium nitrate. The crude product may be purified by distillation. Conversion of 4 to 5 may be conducted as described by Natchev. As above, the product may be purified by distillation. Conversion of 5 to the final desired reagent 6 may be accomplished using known methods (See, for example, Almirante, N. et al. Tetrahedron Lett. 1998, 39, 3287).

An alternate procedure with easier purification methods and higher yields is described by Bellassoued and Majidi (J. Org. Chem. 1993, 58, 2517-2522), illustrated in Scheme 2. Treatment of an aldehyde with reagent 7 in the presence of 0.1 equiv. ZnBr gave the vinylogous aldehydes (acrylaldehydes), in yields ranging from 65% to 95%. Reagent 7 is commercially available.

In certain embodiments, new analogues were prepared using a two-step synthetic method beginning with aryl aldehydes (R—CHO, Scheme 2). Vinylogation of the aryl aldehydes was achieved via treatment with α,α-bis(trimethylsilyl)-t-butylacetaldimine (7) in the presence of ZnBr₂, as described in the literature (Bellassoued, M.; Majidi, A. J. Org. Chem. 1993, 58, 2517), to afford the 3-arylacrylaldehydes R—CH═CH—CHO. The 3-arylacrylaldehydes were converted to the final products via treatment with diethoxyphosphorylacetaldehyde tosylhydrazone (8), as described in the literature (Almirante, N.; Cerri, A.; Fedrizzi, G.; Marazzi, G.; Santagostino, M. Tetrahedron Lett. 1998, 39, 3287).

It will be appreciated that the two-step reaction sequence illustrated in Scheme 2 is general in nature, and one skilled in the art will recognize that the method could be used to prepare analogues in which R represents virtually any type of aryl, alkyl, heteroaryl, or heterocyclic functional group. The following represent non-limiting examples of the synthetic method, and are illustrated in FIG. 1 below.

Scheme 3 shows some exemplary reactants and the corresponding intermediate and product. Following flash column chromatography, the desired intermediates were obtained in 60-95% yields. Conversion to the final analogues using reagent 8 gave compounds falling within the scope of compounds of Formula II.

Using the aforementioned methods, the compounds described below, among others, were prepared.

1.3- and 1,5-Disubstituted Pyrazoles (C(3) and C(5)-Positional Isomers)

In certain other embodiments, compounds of general Formula III of the invention may be synthesized by any of several methods. In certain embodiments, in Method A, illustrated below, 3-bromopyrazole (commercially available) will undergo alkylation or acylation by reaction with an acyl chloride or alkyl halide in a suitable polar aprotic solvent such as dichloromethane and base such triethylamine to form the intermediate compound. Coupling reaction with a boronic acid, using a palladium catalyst, base such as K₂CO₃ or CsCO₃, and warming in an aprotic solvent such as benzene, toluene, or xylene will provide the target pyrazoles. Alternatively, 3-bromopyrazole may be coupled with vinyl compounds in the presence of a catalyst prepared in situ from 2.5% Pd(AcO)₂ with 5% mono-sulfonated triphenylphosphine (TPPTS) in an aqueous solvent such as water and ethanol. (Ref. Genet, J. P., Blart, E.; Savignac, M., Synlett, 1992, 715-717).

As discussed above, 1H-pyrazole-type compounds such as 3-Bromo-1H-pyrazole, typically exist as a mixture of tautomers. Therefore, acylation of 3-Bromo-1H-pyrazole with RC(═O)Cl leads to a mixture of C(3)- and C(5)-positional isomers, as depicted below:

Therefore, method A allows the preparation of both C(3)- and C(5)-positional isomers of compounds of the invention, e.g.:

For example, using Method A, above, for the preparation of a related compound (4-chlorophenyl)[3-(2-(2-thienyl)vinyl)-1H-pyrazol-1-yl]methanone described in U.S. Pat. No. 6,610,726, incorporated herein by reference in its entirety, one may react 3-bromopyrazole with 4-chlorobenzoyl chloride (commercially available, for example, from Aldrich Chemical Co., Milwaukee, Wis.) to provide the first intermediate in Method A. Then reaction of this material with epsilon-2-(thienylethenyl)boronic acid (commercially available, for example, from Combi-Blocks Inc., San Diego, Calif.) forms the desired product. Compounds corresponding to those described in Formulae III^(D1), III^(D2) and II^(D3) herein may be likewise prepared from the corresponding benzoyl chlorides as well as many different types of boronic acid analogs that are commercially available or readily synthesized.

For example, the following procedures were used to prepare 1,3- (and 1,5-) disubstituted pyrazole compounds of general Formula (III).

Example 8

3(5)-[2-(phenyl)vinyl]-1-(4-chlorobenzoyl)-1H-pyrazole. To a solution of the product from Example 7 (3.2 g) in 60 mL dichloromethane was added 5.7 g Na₂CO₃ powder, and the solution was then cooled to 0° C. 4-Chlorobenzoyl chloride (3.2 g) was added dropwise, the ice bath was removed, and the reaction was allowed to stir at room temperature overnight. The solids were removed by filtration, the filter pad was rinsed with dichloromethane, and the combined filtrates were concentration to a small volume. Hexane was added to the concentrated solution, resulting in precipitation of the desired product as a yellow powder, which was collected via vacuum filtration, rinsed with hexane, and air dried (4.7 g): ¹H NMR (CDCl₃) δ 6.72 (d, 1 H, J=1.8 Hz), 6.97 (d, 1 H, J=9.9 Hz), 7.03 (dd, 1 H, J=3.0, 2.1 Hz), 7.14 (d, 1 H, J=2.1 Hz), 7.27 (d, 1 H, J=2.1 Hz), 7.33 (d, 1 H, J=9.9 Hz), 7.49-7.52 (m, 3 H), 8.08 (dt, 1 H, J=5.4, 1.5 Hz), 8.17 (dt, 2 H, J=5.4, 1.5 Hz), 8.39 (dd, 1 H, J=1.5, 0.6 Hz).

In Method B, depicted below, cinnamaldehydes undergo reaction with hydrazides to form hydrazone intermediates. The dianion of the corresponding hydrazones undergo reaction with esters, amides, acid anhydrides, acid chlorides and alkyl carbonates to form target pyrazoles. (ref. Tetrahedron Lett. 1983, 24(31), 3239-3242).

Using the aforementioned methods, the compounds described below, among others, were prepared.

The foregoing are merely exemplary of synthetic routes to the compound of the invention. The foregoing compounds, compositions and methods of the invention are illustrated by the following examples, which are merely exemplary of aspects of the invention and are not limiting.

2) Biological Activity:

1. Assessment of HGF/SF-like activity: The following assay was performed to assess the HGF/SF-like activity of the compounds of the invention. Endothelial cells (HUVECs) were seeded in 48 well plates at a density of 10,000 to 20,000 cells per well in the normal growth medium (EGM-2—Clonetics) containing 2% fetal bovine serum, FGF, VEGF, IGF, ascorbic acid, EGF, GA, heparin and hydrocortisone. The cells were grown normally in the growth medium for 24 hr at 37° C. and 5% CO₂. The cells were then rinsed with RPMI-1% BSA and starved for 1-2 hrs. The stock solutions of the compounds of the invention were made at a concentration of 10 mg/ml in DMSO and diluted in RPMI-1% BSA at a final concentrations of 0.01 micromolar to 25 micromolar. The cells were then washed and treated with the compounds and incubated for another 24 hr at 37° C. Then ³H thymidine (0.5 microgram/ml in RPMI-BSA) was added to the cells and incubated at 37° C. for 4 to 5 hours. The unincorporated thymidine was removed by washing the cells four times with 1×PBS. Then the cells were lysed with 0.5M NaOH for 30 min and the radioactivity counted in the beta counter. A similar proliferation assay using monkey bronchial epithelial cells (4 MBR-5) was also employed.

The following compounds demonstrated activity in the aforementioned assay.

Effectiveness of the aforementioned compounds in various conditions and diseases is described in U.S. Pat. Nos. 7,192,976; 7,250,437; and 7,265,112, all of which are incorporated herein by reference.

2. Expanded therapeutic window—acute myocardial infarction. In the left anterior descending artery (LAD) ligation model of acute myocardial infarction in the normothermic rat, a compound of the invention was found to reduce infarct size and the number of apoptotic cells measured 48 hours after LAD ligation, when compound is administered at the time of infarct or as much as three hours after ligation. In the 3 hour delayed treatment study, infarct size of untreated vs. compound treated rats (single IV dose, 2 mg/kg) was 60% vs. 25%, respectively, and % apoptotic cells 80% vs. 25%, respectively. In another experiment, a delay of 24 hours before starting treatment also reduced infarct size.

3. Expanded therapeutic window—post-infarct ventricular remodeling and heart failure. Animals surviving the LAD ligation model undergo cardiac remodeling during the post-infarct period, and show an increase in ED chamber volume, and a decrease in fractional shortening and ejection fraction. When compound of the invention is administered starting 48 hours after LAD ligation and continuing daily for 9 weeks (2 mg/kg, IP), benefits to the three cardiac function parameters is noted, according to the following table.

Vehicle Treated No LAD ligation ED chamber volume (cm³) 0.8 0.55 0.45 Fractional shortening (%) 15 25 35 Ejection fraction (%) 30 45 65

4. Delayed treatment in renal ischemia. The effect of delayed treatment with a compound of the invention in a normothermic renal ischemia model was investigated. Male

Sprague-Dawley rats were subjected to 60 minutes of renal ischemia, then randomized into a vehicle group (n=11) and a treatment group (n=14). Administration of 2 mg/kg compound, IV, was started 24 hours after reperfusion and then again at 48, 72 and 96 hours after reperfusion. Mortality and renal function were assessed every 24 hours. At 96 hours, survival in the treated group was 50%, vs. 11% in the vehicle group. Serum creatinine and BUN at 48 hours post reperfusion and beyond were significantly decreased in the treatment group compared to vehicle.

5. Model of amyotrophic lateral sclerosis (ALS). The SOD^(G93A) mouse model of ALS was used to evaluate the effect of a compound of the invention on progressive pathology of ALS. Eight-week old mice were administered compound at a dose of 2 mg/kg, IP (n=10) daily starting at age 94 days, when neurofilament degeneration typically occurs, through day 122. Using a hindlimb clinical observation score described in Gurney et al., 1994, Science 264:1772-5, compound treatment significantly improved the pathology score vs. the vehicle-treated cohort (n=10), p=0.016. In addition, a stride test showed that treated animals showed improvement. Survival of the treated animals was also significantly (p<0.05) extended vs. vehicle-treated animals.

6. Oral administration in chronic kidney disease (CKD). The effects of delayed, orally administered compound were examined in a standard and well-characterized mammalian model of CKD. Adult male Sprague-Dawley rats were subjected to 5/6 nephrectomy via ligation of 2 of the 3 branches of the left renal artery and excision of the right kidney. Three days after ablation, blood samples were obtained and serum creatinine (SCr) determined. Rats with SCr values between 0.8 and 1.2 mg/dL (baseline SCr for rats is 0.2 mg/dL), indicating adequate and sustained renal ablation, were entered into the study. One week following surgery, animals were randomized to vehicle (n=15) or compound (45 mg/kg, PO, QD, n=15). Six weeks following surgery (i.e. 5 weeks into treatment) animals were sacrificed. Urine and kidney samples were obtained for evaluation of proteinuria, histopathology and pharmacodynamic markers of compound action. Oral administration of compound was found to be therapeutic in CKD, attenuating mortality, reducing proteinuria and kidney collagen content (hydroxyproline and Sirius red staining). In another study, daily oral treatment of 15 or 45 mg/kg (n=15; vehicle n=15) was started 2 weeks after surgery and continued for 10 weeks. At 10 weeks, evaluation showed similar survival in both treatment groups (80%) vs. untreated animals (45%), and a dose-responsive reduction in kidney collagen content.

7. Oral administration attenuated proteinuria in metabolic syndrome. Three-month old obese male ZSF1 rats were randomized to vehicle or compound (45 mg/kg, oral, daily, n=5/group). Prior to randomization these rats exhibited severe spontaneous hyperglycemia (−450 mg/dL) and hypercholesterolemia (ca. 1500 mg/dL). After 10 days of treatment, 24-hour proteinuria was significantly reduced.

8. Delayed treatment in liver fibrosis. Adult male SD rats were administered thioacetamide (TAA, 200 mg/kg, ip), thrice/week for 4-8 weeks until the appearance of hepatic fibrosis. Treatment with inventive compound (ip, PO) concommitant with or subsequent to TAA administration attenuates progression of hepatic fibrosis—reducing liver profibrotic genes and liver collagen content. The following protocols were studied all of which were found to be benefitted from treatment: 1) liver fibrosis induced with TAA during weeks 1-8, IV compound treatment during weeks 9-12, 2) liver fibrosis induced with TAA during weeks 1-6, IV compound treatment weeks 4-8, 3) liver fibrosis induced with TAA during weeks 1-8, oral compound treatment weeks 9-12, and 4) liver fibrosis induced with TAA during weeks 1-4, oral compound treatment weeks 5-9.

9. Muscular dystrophy. In a genetic murine muscular dystrophy model, administration of a compound embodied herein for 2 months, daily via intraperitoneal injection reduced levels of creatine kinase, a hallmark of the disease.
